ABBA’s hits to life

Mamma Mia! The Party is a theatrical dining experience that brings ABBA’s hits to life.

Since opening in August 2019, Mamma Mia! The Party London has welcomed over 700,000 guests across over 1,500 performances, and has been visited by guests from 110 countries.

In the show, as the sun sets on the Greek island of Skopelos, guests take their seats at Nikos’ family-run taverna where they enjoy a delicious four-course Greek feast, whilst a romantic, hilarious story unfolds all around them, written by Sandi Toksvig.

The story is set to the timeless songs of ABBA, including Mamma Mia, Dancing Queen and Waterloo.

Following the performance, guests are encouraged to sing and dance the night away at a glittering ABBA disco.

ABBA in London

London remains a major hub for ABBA fans, who can also experience the original stage musical Mamma Mia! at the Novello Theatre in the West End, as well as the groundbreaking concert ABBA Voyage at the ABBA Arena in East London.
